The existing literature often lacks the incorporation of unconventional boundary conditions, and this study addresses this issue by extending the application of the Fokas method to the higher-order Gerdjikov-Ivanov equation on the half line (\u2212\u221e,0]. We have demonstrated the exclusive representation of the potential function u(z,t) in the higher-order Gerdjikov\u2013Ivanov equation through the solution of a Riemann\u2013Hilbert problem. The characteristic function is partitioned on the complex plane, and we obtain the jump matrix between each partition based on the positive and negative values of the partition as well as the spectral matrix determined by the initial data and boundary value data. The findings suggest that the spectral functions are not mutually independent; instead, they conform to a global relationship. The novel aspect of this study is the application of the Fokas method to a previously unexplored case, contributing to the theoretical and practical understanding of complex partial differential equations and filling a gap in the treatment of boundary conditions.<\/jats:p>","DOI":"10.3390\/sym16101258","type":"journal-article","created":{"date-parts":[[2024,9,25]],"date-time":"2024-09-25T16:16:37Z","timestamp":1727280997000},"page":"1258","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Riemann\u2013Hilbert Approach to the Higher-Order Gerdjikov\u2013Ivanov Equation on the Half Line"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-3284-0965","authenticated-orcid":false,"given":"Jiawei","family":"Hu","sequence":"first","affiliation":[{"name":"College of Mathematics and Systems Science, Shandong University of Science and Technology, Qingdao 266590, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Mathematics and Systems Science, Shandong University of Science and Technology, Qingdao 266590, China"},{"name":"Department of Fundamental Course, Shandong University of Science and Technology, Taian 271019, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1411","DOI":"10.1098\/rspa.1997.0077","article-title":"A Unified Transform Method for Solving Linear and Certain Nonlinear PDEs","volume":"453","author":"Fokas","year":"1997","journal-title":"Proc.
